Photocatalysis

Characteristic of the working group Photocatalysis:

Group deals with the development of photocatalytic materials, which have application in the  cleaning of air and waters, in the formation of so-called self-cleaning surfaces and in the solar decomposition of water into hydrogen and oxygen.
